Adam's Ribs - S3-E11
Revealing mistake: While Hawkeye's in the mess tent leading the protest shouting "we want something else" he climbs the tent pole, and in two of the wideshots the camera has panned a bit too far to the right, and we can see the edge of the tent facade set at the top right corner of the screen.
Aid Station - S3-E19
Visible crew/equipment: As Hawkeye walks into the Aid Station, the shadow of the camera plays across his entrance. Also, the area he walks through is extremely well lit, despite the fact the sun is behind the station, indicating stage lighting.
Adam's Ribs - S3-E11
Revealing mistake: As Radar, Henry, Klinger and Trapper get up to answer the emergency call, the outside background can be seen in the upper right corner of the shot, showing it was done on a sound stage.
Adam's Ribs - S3-E11
Character mistake: As Hawkeye obsesses about ribs, Henry says that he met Lorraine at the Dearborn Street Station. But while watching home movies sent to him, Henry said he met her at a freshman mixer.
Continuity mistake: When Margaret asks Frank for cash to help her sister get an apartment, he asks about her father leaving her anything, implying that her father is dead. Later on, we see her father when he comes to visit her in another episode.
Continuity mistake: When Henry kisses Margret, she grabs her hat. In the reverse shot, her hand is around Henry's neck. After the next cut, it's on her hat again. (00:20:00)
Continuity mistake: In the shot where Hawkeye presents the Spam lamb to Henry, he sets it down, and Henry asks him what it is. Behind Henry, you can see Hawkeye's shadow - and see his lips mouth the word "A Spam lamb". The camera then changes to a close-up of Hawkeye, saying "A Spam lamb".
Visible crew/equipment: As Col. Whiteman leave Sentry Post 1, where Klinger is, the boom mic is reflected on his helmet.
Continuity mistake: In the Swamp, Pak pulls out a stack of money, holding it by the end. In the closeup, he is holding it by the middle.
Continuity mistake: On The Bus, as Hawkeye raises Mrs. Kwang's legs for delivery, Radar is turning around, hiding his face. In the close up, Radar turns around again.
White Gold - S3-E23
Continuity mistake: As the men are sneaking by the tents, Hawkeye's voice is heard coming from a tent with opaque windows. A minute later in all the commotion, he's seen coming out of the Swamp.
Audio problem: As Trapper opens the door to the swamp and the football flies in, a splash is heard as if it hit a tub of water, followed by the sound of a high, fluted vessel filling with water. Neither of those sounds make sense in this case. (00:07:00)
Revealing mistake: As Hawkeye calls for quiet in the officers' club, Henry pulls the tonearm off the record player, it comes away trailing a long wire behind it. Why would it even have a long wire to trail? After all, wire costs money too. It's not like the tonearm is designed to come off and be used remotely. My guess is: they lengthened it, so the shot could be taken several times without repairing the record player every time. Now, WHY they would do it that way and not simply use a dud record player is beyond me. (00:20:55)
Mad Dogs and Servicemen - S3-E13
Factual error: While Radar's lying in bed, Margaret reads a letter to him which was written by Wanda McCandless, and in the letter Wanda mentions that her favorite songs are "Pretty Thing..." by Bo Diddley, and "Oh, The Wayward Wind..." by Gogi Grant, but the problem is these songs were written and recorded in 1955 and 1956, years after the Korean War was already over in 1953.
Visible crew/equipment: While Trapper and Hawkeye are already in Henry's office Radar and Henry walk in, and just as Henry says, "Everything in this country disappears except me," the shadow of the boom mic can be seen moving across the wall at the top right side of the screen.
Adam's Ribs - S3-E11
Continuity mistake: While Hawkeye leads the protest in the mess tent shouting "we want something else," there are two closeup shots of the table where Klinger and Radar are seated, and Klinger's white evening purse is missing, but in the previous and following wideshots the purse is hanging on his arm.
Adam's Ribs - S3-E11
Continuity mistake: When Hawkeye's in the mess tent holding the food tray the succotash is on the left and potatoes on the right with a space in the middle, so when Igor serves him creamed corn offscreen the corn should be between the potatoes and succotash, but when Hawkeye's having the fit and walks away from Igor, the potatoes (a higher mound) are now in the center space between corn and succotash.
Visible crew/equipment: As Hawkeye and Trapper sit down to talk with McShane, the shadow of the tip of the boom mic can be seen on the door on the right side of the shot. (00:08:25)
Visible crew/equipment: At the chopper pad, as the scene plays out, reflections of the lighting rigs can be on the chopper canopy.
Answer: It is actually Cencompac for Central Command of the Pacific. It is like the headquarters for all military activity in the Pacific Region (Japan, Korea, Okinawa, etc. The newer version of that is United States Pacific Command (USPACOM).
EMTurbo
And the abbreviations were used mainly by the Navy. Especially CENCOMPAC.
